Hepatocellular cancer: a guide for the internist

Area of Science:

• Hepatology
• Oncology
• Gastroenterology

Background:

• Hepatocellular cancer (HCC) is the third leading cause of cancer mortality globally.
• HCC incidence is increasing in the US, driven by hepatitis C virus (HCV) infection.
• Key risk factors include hepatitis B virus (HBV), HCV, and heavy alcohol use leading to cirrhosis.

Purpose of the Study:

• To review screening, diagnosis, and referral practices for hepatocellular cancer.
• To equip internists with timely management strategies for HCC patients.
• To emphasize the importance of early detection in improving prognosis.

Main Methods:

• Review of current diagnostic criteria, including radiologic, serologic, and histopathologic methods.
• Discussion of treatment options, highlighting liver transplantation as the only definitive cure.
• Emphasis on screening protocols for high-risk individuals, recommending liver ultrasound every six months.

Main Results:

• Most HCC cases are diagnosed at advanced stages, necessitating prompt intervention.
• Prognosis is significantly influenced by the stage of diagnosis and underlying liver function.
• Effective screening and timely referral are critical for managing HCC.

Conclusions:

• Early detection through regular screening is vital for improving hepatocellular cancer outcomes.
• Internists play a key role in the timely diagnosis and referral of at-risk patients.
• A multi-faceted approach combining screening, accurate diagnosis, and appropriate referral is essential for managing HCC effectively.
